Why did Sasuke overuse his Mangekyou Sharingan?

[Solo]

Exactly. Anyone who knows Sasuke, knows that he would never kill anyone who didn't need to die. Sasuke was more careful than this, he made it very clear that the only person who needed to be killed was Itachi, however there was a few mistakes along the way, like Orochimaru and Deidara.

But those just happened in reason because he didn't need Orochimaru anymore, and let's be real that dude was a psychopath. And Deidara basically killed himself.

Sasuke does not just take lives because he can, so when he entered the Kage Summit with the intent to kill anyone in his path because he just can, it was rash and stupid. There was no game plan, no escape plan just in case, no worries about anything else.

Anyone can see that Sasuke was not in peak condition (mentally) so I don't see the point of making excuses for the situation. I can assure you that the last thing Sasuke would do reasonably is attack the Five Kage's all at once, he knows better.

Sasuke never intended on fighting anyone, but Danzo. Sasuke's plan was never stated, but it was assumed they would attack Danzo on his way back to the village to avoid the attention of the other Kage and Samurai. According to their talk about what to do.

Sasuke did not go and start attacking. Zetsu was with him one second, disappeared, and snitched. Plus, after Zetsu betrayed him. Running really was pointless. Of course, lets run from the sensory ninja and one of the fastest Shinobi at the time.

No, Sasuke did not go with the intention to kill anyone in his path because he didn't even kill the first samurai. Sasuke was more than likely getting more and more ignored until he just said "**** it". He even warned the samurai, that's he's pissed off and won't hold back.

The mission probably had a low success rate, but I highly doubt Sasuke was going in blindfolded.

This. The plan was to tail Danzo out of there. It was never to raid the Kage summit. I would like a scan on this. There isn't any. It's made up fan fiction to lay dirt on Sasuke. Once the jig was up, there was no escape as the Kages had sensors with them and the exits were blocked by Samurais. It was kill or be killed. And this was Obito's plan all along.

In fact, Ninjas are trained to infiltrate Villages and gather intel. Have people forgotten Ibiki's test? Kisame's flashbacks? Zabuza's story? Danzo's works in the shadows etc. etc.? So, to state that what Sasuke did was wrong, well, might as well just disregard the whole training of a Shinobi; a solider trained for Espionage and assassinations, heh.

Zetsu didn't even make himself known until Sasuke got in a situation he couldn't escape from.

I have no idea what you were talking about, stop making up alternative facts :lol

Sasuke went in and started attacking people left and right. Zetsu being a jack-ass doesn't excuse the fact that Sasuke was murdering the neutral samurai, and they had a sensor who could of easily given away the situation before Zetsu did.

No matter what happened he was going to get caught cause he was going in angry. No one is a tactician when they are fighting on strong emotions.

Where is he attacking people "left and right" before Zetsu didn't give his position away and the sensors didn't start looking for him, along with the Samurai? He isn't even moving then. No one had any ****ing clue that Sasuke was even there, let alone any 'situation' you are referring to. What are you talking about? Heck, Karin outright states that they would be captured in no time. Fighting back at that moment and killing Samurais was the smartest decision to take in that situation.
